HEATING STOVE.

Application T0 aZZ whom it may concern.' y

Be it known that I, GEORGE G. SCARBOR- OUGH, a citizen .of the United States, residing at Girdletree, in the county of Worcester and State'of Mav vland, have'invented certain new.l and use ul Improvements in Heating Stoves, of which thefollowing is specification. i

This invention relates'to heating'stoves, and is an improvement over the construction shown inmy prior Patent No. 1,343,645, dated June 15, 1920.

Tn the said prior patent, I have disclosed an outer shell, an inner shell spaced therefrom and forming a passage for the products of combustion, and a central fuel feeding magazine arranged within the shell.

An object of the present invention is to lprovide an improved construction of i11- ner shell and fuel feedin magazine which will prevent the fuel from lurning above the lowei.' end of the magazine.

A Jfurther object is' the provision of anin-y ner shell having an inclined bottom extending to the bottom *of the fuel feeding magazine and forming a restricted passage or the passage of the products of combustion.

ln the accompanying drawings, I have shown one embodiment of the invention. ln this showing:

Figure 1 is a central vertical sectional view,

Figui-Q72 is a perspective view of the fuel feeding magazine,

Figure 3 is a similar view of the inner shell,v and, J A

Figure 4 is a horizontal sectional view on line 1f-e1 of Figure 1.

Referring to the drawings, the reference numeral 1 designates a cylindrical body portion having a grate 2 arranged therein. The grate divides the body portion of the stove into a lire box 3 and an ash pit 4. The bodj,1 portion of the stove may be supported on suitable legs 5. with a. door 6, for

The ash pit is provide v the removal ot' ashes and The u4 per en of the body ortion is provided vwitv 'an annular heat alisorbing .1nd radiating element 7, having a substanhally thiclc cross sectional area. This element is provided with .An outer shell 9 this Harige, forming a gas tight joint between the shell and the body p0rtion. An inner shell 10 is arranged within Hm.

forming an annular passage 11 for the escape of gases and products of combustion. The upper end of the inner shell is open and is adapted to be partially closed by a cover l2.' The inner shell is further provided with legs 13, projecting downwardly and yadapted to rest on the Han e 8. These legs are of a width substantily equal to the width o'f the annular space 11 and serve as spacing bars to retain theinner shell and outer shell in the desired position with respect to each other. Beyond the point where the legs project the'inner shell is provided vwith an inclined bottom 14." 1 A fuel feeding ma azine'v15' is arranged of. the inner shell'. As shown, the progided with a central.

centrall incline bottom is openin adaptedA to'recev'ethe v,lower en ingh'niagazf Y gfc'lhe Hange '16 1s arranged-ont ete'` rien-*ofthe magazine adjacent the-botmmand adapted to rest upon the inclined bottom of the inner shell to support-the lower end of the' magazine. of the ma azine extends 12, the opendiameter than throug an opening in the 1i ing beingof slightly larger the magazine, as shown. A sealin n 17 is larranged onthe lid and is a' apte to snugly receive the upper end of the magazine. The s ace between the inner shell and the fuel fee in magazine forms a. dead-air chamber 18. his space sjof a substantial 'cross sectional area and serves asan' effective heat insulating means between the magazine and the passage 11. The stove is provided with a. top 19. The outer edge of t e to is provided with a depending Harige 20 an an outwardly extending Hangs 21, The depending Harige and the Harige outer casing. The outer casing with ears 20 and bolts 21 through the Harige 21 and these ears.

filled with' from the-inner shell,

fits within the outer casing through the passage 11 to the stae c 25. The -space 18 effectively insulates the tubular magazine from the heated' passage. By providing the inclined lower end of the inner shell, the heat is reta-ined in the fire box and a relatively small passage is providedl between the body portion of the stove and the inclined bottom of the inner shell which communicates with the bottom of the passage 11. The inclined bottom. further serves to throw the heat outwardly to the heat absorbing and radiating element 7, and thus to the room to be heated. By throwing the heat outwardly, the fuel in the magazine is kept at a relatively low temperature and formation of gas is prevented. The elimination of gassing is an important feature of the invention and is due to the ine-lined bottom 14.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example\of the same, and that various changes in the shape,v

size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the sub joined claims.

Having thus described my invention, I claim i 1. In a self-feeding stove, the combination with an outer shell and an inner shell arranged therein and spaced therefrom, said inner shell heilig provided With-an inclined bottom having a central opening.v of a fuel magazine arranged Within said inner shell and terminating substantially in alinement with the bottom of said inner shell, means for supporting said fuel magazine. a top having an outer flange to engage said outer shell and an inner flange to receive said fuel magazine, and a cover for said magazine rest-ing on said top.

2. In a self-feeding stove, the combination with an outer shell and an inner shell arranged therein and spaced therefrom, said inner shell being provided with an inclined bottom having a central opening, of a fuel magazine arranged Within said inner shell and terminating substantially in alinement with the bottom of said inner shell, said fuel magazine being provided with a circumferential flange on its exterior adjacent the bottom thereof adapted to be engaged by the inclined portion of said inner shell to support it, a top having an outer flange to engage Said outer shell and an inner flange to receive 'the upper end of said fuel magazine, and a cover for said magazine resting on said top.

In testimony whereof, I affix my signature.

GEORGE G. SCARBOROUGH.
